English demands that its users know more than just the meaning of a word.
They also must know how it’s used. It’s not okay to slap just any words together. Some have special ‘partners’.
While subbing an article yesterday, I happened upon the phrase ‘pay their condolences’. I knew instinctively that condolences were not paid. However, I forgot for a second what it was that you did with them.
So of course, you offer them. Thus the phrase was corrected to ‘offer their condolences’
While gathering information on the matter, I discovered that one can offer condolences in the singular, as in I offer my condolence. There is also the verb, to condole.
Lifesomundane.net has explained the difference between the singular and plural usage so well that I’ve just copied it in.
“Now this is a tricky one. I have always preferred ‘condolences’ because that is how I often hear it from native English speakers. It is not, apparently, as straightforward as I used to think.
First of all, the word condole is derived from the Latin ‘condolere,’ meaning to ‘suffer with one another.’ It means to ‘express one’s sympathetic grief, on the occasion of someone’s death.’ (Advanced English Dictionary)
Condolence, therefore, is an expression used to commiserate or sympathise with a person who has just lost a loved one.
To get back to the gist of the matter, does one say ‘condolence’ or ‘condolences’ when expressing sympathy to the bereaved?
Weeping over loss
If used as part of an adjective phrase, there is no question that ‘condolence’ is more correct. Hence, one gives a ‘message of condolence’ rather than a ‘message of condolences.’
There also is no question when condolences are offered to the bereaved on behalf of a group of persons. Hence, you can say my family’s, my company’s or my office’s condolences. Likewise, one can just say OUR condolences.
The tricky part is when one says MY condolences. There seems to be something not quite right about a singular person offering the plural of condolence on his or her behalf alone.
However, as a matter of convention, it is perfectly correct to do so and this is, in fact, how native English speakers condole with the bereaved.
Similarly, ‘my sympathies’ is often preferred to ‘my sympathy,’ the latter grammatically correct but not quite sounding so conversationally.”
Most online English dictionaries that I referred to before writing this article do not state outright that ‘condolences’ is more correct than ‘condolence’ when used by a person on behalf of himself alone.
Instead, what they say is that ‘condolences’ is how the word is OFTEN used to express sympathy when somebody dies.
To conclude, ‘my condolence’ is perfectly correct and especially so from the grammatical point of view. That said, ‘my condolences’ is just as correct and particularly so because this is how it is often stated by native English speakers.
